TIDE-MOTOR.

To all whom it may concern: Be it known that I, PERLEY HALE, a citi' zenof the United States, and a resident of the city of Chicago, county ofCook, and tate of Illinois, have invented certain new and usefulImprovements in Tide-Motors, of which the following is a specification.

My invention relates to tide motors and particularly to the class, ofsuch motors which is acted upon both by the waves and the tide.

The object of this improvement is to provide a device of the charactermentioned, which will be simple in construction and etlicient inoperation.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter fully descrlbed and claimed.

The invention will be best understood by reference to the accompanyingdrawings, and in which,

Figure 1 is a plan view with a corner portion removed to show thereinforced construction of a tide motor built in accordance with myinvention, Fig. 2 is a vertical section of the same taken on line 2-2 inFig. 1, Fig. 3 is a. similar view taken on line in Fig. 1, Fig. t is ahorizontal section taken on line it in Fig. 3, Fig. 5 is a part verticalsection and partside elevation of a fragment showing the connectionbetween the front of the motor basin and top of the inclined wall, andFig. 6 is a plan view of the clock gears used for taking the power fromthe pinion-and-rack of the float.

The preferred form of construction, as illustrated in the accompanyingdrawings, comprises a motor basin in which is mounted a verticallymoving float and water turbines, a waste basin in communication withsaid motor basin and an inclined wall on the seaward side of the motorbasin and provided with communications for the passage of water throughthe device. It is preferred to make at least two motor basins and twowash basins, inclined walls, and waste basins, as shown in the drawings.

The Walls of the entire device are preferably composed of reinforcedconcrete and the inclined wall 7 is provided with supporting ribs 8 andposts 9 to give it strength. The wall 7 is provided with openings 10through which the water enters from the rising tide. The motor basin 11is provided with intake valves 12 through which water Specification ofLetters Patent.

enters from the chamber covered by the inclined wall 7 and such intakevalves 12 are made in such a manner as to permit of water entering, butwill not allow its flowing out of the motor chamber 11.

The front orseaward wall of the motor chamber 11 is provided with arecess 13 and such recess is provided with a peripheral groove 14: intowhich is mounted a gate 15 for vertical sliding. A door 16, preferablyof metallic construction, is hinged to the lower side of recess 17 inthe inclined wall 7,

as at 18, to permit of vertical swinging of such door. Said door 16 isconnected with the gate 15 by means of a slot-and-pin connection toraise and lower the gate 15 upon swinging the door 16. Aratchet-and-pawl 19 is provided on the pintle of the hinge 18 of thedoor 16 to maintain the door 16 in de sired positions. A crank 20 isprovided on the end of the pintle of the hinge 18 by which the door 16is manually swung on its hinges.

A baffle plate 21 is formed in the motor basin 11 in the upper portionthereof and extends longitudinally with the seaward side of said motorbasin to prevent splashing of water on the float 22 which is mounted inthe motor basin for vertical movement therein. The float 22 is providedwith a rack 23 which engages a pinion 2 1 on a clock movement 25, whichfurnishes a means for taking power from the'vertical movement of thefloat 22. A suitable bridge 26 is provided overthe motor basin 11 tosupport the float guiding racks 23 and the clockwork mechanism 25.

Near one end of the motor basinll 1s provided a number of turbines 27which are in,

the motor basin 11 which permits the waste water after passing throughthe turbines to pass away from the motor chamber 11 and into the wastebasin 33. Such waste basin 33 is provided with outlet doors 34 whichpermit of the waste water leaving the waste basin as the tide recedes.\Vhen two or more of the devices are built together as illustrated inthe drawings, the waste Water passages 32 are provided withcommunications 35, as clearly illustrated in Figs. 3 and 4, and providedwith gates 36 so that the waste water may be emptied in the desiredbasin. VVindlasses 37 or other manually operative means are provided tooperate the gates 36 in the communications 35 to control suchcommunications; .f

In operation, the tide rising, enters the openings 10, passesthrough thechamber between the inclined wall 7 and the seaward wall of the motorbasin 11, passes through the intake valves 12 and upon rising in themotor basin 11, raises the float 22, thereby imparting motion to it andsuch motion is communicated to the clock gears as already described.Upon o ening of the valves 30 the water turbines 2 will be operated bythe water passing from the motor basin into the waste passages 32 andpower may be taken from such water turbines through their shafts 28: Thewater then passes from the waste passages 32 into the waste chamber 38and remains in such waste basin until the tide begins to recede, when itpasses out through the outlet valves 34.

The doors 16 are designed to be raised and lowered to control thepassage of waves therein into the motor basin 11. It is intended toraise the doors 16 proportionately with the height at which the wavesare running to prevent excessive agitation in the motor basin ll.

lVhile I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails as set forth, but desire to avail myself of such variations andmodifications as come within the scope of the appended claims.
